Product Description

The Invidia HS17CHB7GM2ST is a Gemini R400 cat-back exhaust built for the 2017-2021 Honda Civic Hatchback across LX, EX, Sport, and Sport Touring trims, all of which share the same 1.5L turbocharged engine platform. Specifically designed to fill the sound gap between Invidia's Q300 and N1 systems, the R400 muffler delivers a unique, aggressive exhaust note throughout the entire RPM band without the harsh cabin drone some aftermarket systems introduce at highway speeds.

Increased piping diameter and smooth mandrel bends improve exhaust flow over the restrictive factory system, while 304 stainless steel construction throughout stands up to years of daily driving and harsh climates. The system connects directly to the factory primary downpipe and includes 2 mufflers plus a mid-pipe resonator, exiting through dual 4" titanium burnt exhaust tips that give the rear bumper a distinctive, finished look.

Exhaust hangers are welded onto the factory hanger locations for an OEM-like fit, and the kit includes all gaskets, hardware, and hangers needed for a direct bolt-on installation. Backed by Invidia's 1-year warranty, this Gemini R400 system is built for Civic Hatchback owners who want a genuine step up in sound and flow without moving into full aftermarket downpipe/turbo-back territory.
